Pre-Workout Supplement Guide: What Actually Works
Most pre-workouts are overpriced caffeine. Here’s what ingredients actually matter.

Effective Ingredients
| Ingredient | Effective Dose | Purpose |
|---|---|---|
| Caffeine | 150-300mg | Energy, focus |
| Creatine | 3-5g | Strength, power |
| Citrulline | 6-8g | Pump, blood flow |
| Beta-Alanine | 3-5g | Endurance |
| Betaine | 2.5g | Power output |
Caffeine: The Foundation
Caffeine is the most effective pre-workout ingredient:
- Improves power output
- Increases endurance
- Enhances focus
Dose: 150-300mg (or 3-6mg per kg bodyweight).
Note: Coffee works too (~100mg per 8oz).
Citrulline: For Pumps
Increases nitric oxide production for better blood flow:
- L-Citrulline: 6-8g
- Citrulline Malate: 8-10g (2:1 ratio = ~5-6g citrulline)
Most pre-workouts underdose this. Check labels.
Beta-Alanine: For Endurance
Buffers lactic acid for longer high-intensity work:
- Dose: 3.2-5g daily
- Timing: Doesn’t matter (saturation over time)
- Side effect: Harmless tingling (paresthesia)
Ingredients That DON’T Work
- BCAAs in pre-workout: Redundant if eating protein
- Underdosed citrulline: 3g does nothing
- “Proprietary blends”: Hide actual amounts
- Exotic stimulants: Often sketchy, unnecessary
What “Pump” Matrixes Hide
Many pre-workouts list impressive-sounding blends but underdose effective ingredients:
| Ingredient | Effective Dose | Common Pre-Workout |
|---|---|---|
| Citrulline | 6-8g | Often 1.5-3g |
| Beta-Alanine | 3.2g+ | Often 1-2g |
| Betaine | 2.5g | Often 1g |
DIY Pre-Workout (Better Value)
Buy ingredients separately:
- Caffeine pills: $10 for 100
- Bulk citrulline: $20 for 100 servings
- Bulk creatine: $15 for 100 servings
- Bulk beta-alanine: $15 for 100 servings
Total: ~$0.60/serving vs $1.50+ for pre-made.
Best Commercial Pre-Workouts
| Product | Transparency | Dosing |
|---|---|---|
| Transparent Labs BULK | Excellent | Clinical doses |
| Legion Pulse | Excellent | Clinical doses |
| Gorilla Mode | Good | Strong doses |
Timing
- Caffeine: 30-60 min pre-workout
- Citrulline: 30-60 min pre-workout
- Creatine: Any time (daily saturation)
- Beta-Alanine: Any time (daily saturation)
Verdict
Most pre-workouts are overpriced. Key is caffeine + citrulline at proper doses.
Buy transparent labels with clinical dosing, or make your own.
Skip: Proprietary blends and exotic stimulants.
